Hey all,
If you were on a $500 budget for test equipment for IEM (in-ear monitors) development, how would you proceed?
Are there standardized test procedures and equipment?
I'm not afraid of DIY if there are some budget saving shortcuts that work just as well as off the shelf.
Thanks all!

Hi,
Researching hearing aid testing should give you some standards.

I need some help weeding through the hardware options.
I'm looking at the QA400... but won't I need a headphone amp or a mic preamp as well? How do I make sure these are 'flat' or how do I calibrate for these?
Does it matter which measurement mic I get as long as its calibrated?
Anyone know where one can get IEC 711 2cc and 0.4cc couplers on a budget?

Look for Audio Precision tech note TN107 for a description of how this is done.
Unfortunately, a HATS is very expensive. Search for KEMAR and bruel & kjaer 4128-C. Out of my price range but reading about them is very instructional.
I assumed testing earphones was simple - put the earphone up to a calibrated mic and run a sweep. Turns out (like most things in life) - its complicated.

Hey xmo, thanks for the heads up on that tech note. AP seems like an excellent resource.
I just assumed that you wouldn't need a fake pinna for custom fit in ear monitors. Wouldn't it be better to stickytack them to a IEC 60711 coupler? That would mimic the seal provided by a custom fit better than an 'average' fake pinna would I would think. 🙂
It seems like the GRAS 43AC is the way to go for something off the shelf, but it's tough to pony up the cash for it.
The IEC 60711 spec should specify the dimensions for the IEC 2mm coupler, right? Does anyone have access to the coupler specs?
